134804-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134804-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,0 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134804-57:
(8*1)+(7*3)+(6*4)+(5*8)+(4*0)+(3*4)+(2*5)+(1*7)=122
122 % 10 = 2
So 134804-57-2 is a valid CAS Registry Number.
